If you are among the estimated 90 percent of network managers considering using a software-defined approach for their WAN, you probably already know that SD-WAN can unify network connectivity across hybrid cloud networks, provide remote application deployment and enhance application performance. Put simply, SD-WAN capabilities are transforming network design. If IDC’s predictions bear out, SD-WAN will grow to be more than an $8 billion industry by 2021.
Flexibility to Leverage and Enhance Existing Network Technology
Traditional legacy networks, with their manual configurations and long lead times, are simply not equipped to handle the digital technology that has revolutionized the way businesses operate. As more applications move to the cloud, network capabilities are being stretched even further.
Today’s SD-WAN technology allows for managing the WAN through a software application. This allows businesses to lower their costs and create efficiencies without having to replace their existing hardware. SD-WAN can benefit businesses of almost any size, but it can be particularly valuable for large companies with users in multiple geographic locations using cloud-based applications. Using one management console, IT departments can define and apply performance and security policies across the network, rather than sending cloud traffic through a traditional hub and spoke point of access configuration.
What to Consider When Evaluating SD-WAN
Core capabilities provided by most SD-WAN vendors today allow businesses to leverage different network connections, provide direct internet access, and drive and define network paths based on the business’ unique needs. Beyond the basics, SD-WAN providers are also adding the following capabilities:
In most installations, the SD-WAN’s firewall and a VPN provide sufficient security. Businesses requiring the use of more robust security measures for confidential traffic can use cloud-based security tools, with the underlying business rules dictating which traffic uses which set of security parameters.
Managing the Digital Experience
Integrating digital experience management tools into the SD-WAN can give your business’ IT teams better control over cloud-based applications, allowing them to identify and address potential performance issues quickly. SD can enable dynamic bandwidth allocation for application traffic efficiency.
Integrating SD-WAN with the Public Cloud
SD-WAN can also be deployed and integrated with public clouds, which can help manage your business’ application’s traffic in and out of the cloud. SD WAN can support transport-agnostic types of connectivity — MPLS, Ethernet, cellular and broadband, for example.
